Filing a notice of change Ontario sounds simple — until it’s rejected, delayed, or causes compliance issues months later.
If your corporation changes directors, officers, or its registered office address, you’re legally required to update the government. But many business owners make avoidable mistakes when they file a notice of change Ontario, especially under the current Ontario Business Registry (OBR) system.
This guide walks you through common errors, how to avoid them, and how to file correctly in 2026 — step by step.
What Is a Notice of Change in Ontario?
A Notice of Change is a mandatory filing under the Business Corporations Act (OBCA) when an Ontario corporation changes:
Directors
Officers
Registered office address
Official email address
Business activity
This filing is submitted through the Ontario Business Registry (OBR). It must typically be filed within 15 days of the change.
When Do You Need to File a Notice of Change Ontario?
You must file if your corporation:
Appoints or removes a director
Appoints or removes an officer
Changes its registered office address
Changes official email address
Changes its primary business activity
⚠️ Deadline: Within 15 days of the change under the Ontario Business Corporations Act (OBCA) and the Ontario Not-for-Profit Corporations Act (ONCA).
Failing to file on time may result in compliance issues, penalties, or complications during financing or corporate transactions.
Common Mistakes When Filing a Notice of Change in Ontario
1. Missing the 15-Day Filing Deadline
Many corporations wait until year-end filings — that’s incorrect.
Why This Is a Problem:
Technically non-compliant
May affect financing or due diligence
Can cause issues with the bank
Causes discrepancies in corporate searches
How to Avoid It:
File immediately after board approval
Set internal compliance reminders
Work with a service provider who can get this filed quickly
2. Filing the Wrong Type of Change
There is confusion between:
Each serves a different purpose.
Filing Type | Purpose | When Required |
Notice of Change | Update directors/officers/address | Within 15 days of change |
Articles of Amendment | Change corporate name, share structure | Structural corporate change |
Annual Return | Confirm yearly info | Annually |
3. Incorrect Director Information
Common errors include:
Misspelled names
Duplicating entries
Incorrect residential address
Not staying within minimum/maximum director requirements
4. Not Updating the Minute Book
Many business owners assume filing is enough.
It’s not.
Your corporate minute book must reflect:
Director resignation letters
Board resolutions
Officer appointment resolutions
Updated registers
Failure to update internal records can create major legal exposure during audits, litigation, or sale.
5. Confusing Ontario and Federal Corporations
Ontario corporations file with the Ontario Business Registry.
Federal corporations file under the Corporations Canada governed by the Canada Business Corporations Act (CBCA).
But, a Federal Corporation may also need to file with the Ontario Business Registry to update their information with the Province.
6. Using Outdated Filing Methods
Before 2021, filings were paper-based. Now, Ontario uses the online OBR Portal system.
You may see others still referencing:
Fax submissions
Old Service Ontario forms (Form 1 Notice of Change)
In-person filings
In 2026, filings are completed digitally through the Ontario Business Registry portal or registered intermediaries, like Launch a Business.
7. Not Verifying Registry Records After Filing
Just because you submitted doesn’t mean it processed correctly.
After your Notice of Change, you may want to:
Order a profile report
Confirm changes appear correctly
Save confirmation documents
You can obtain corporate profile reports through the Ontario Business Registry or Launch a Business.
